emana e? carcasses, 01 KETCHIKAN, DISTRICT 0 ALASKA- COOKING DEVICE.

Be it known that I, Gnoner. H. CAUGH- BEAN, a citizen of the United States, and a resident of Ketchikan, in the District of Alaska, have invented certain new and useful Improvements in Cooking Devices, of which the following is a specification.

- My invention relates to improvements in cooking devices, especially those in which fish, vegetables or other articles of food are to be heated in the cans in which they are are fed and discharged automatically.

an inclined shaft 1, which is journaled in Other objects andadvantages will appear in the following specification and the novel features of the device will be pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this application in which similar reference char acters indicate like parts in the several views, and in which- Figure 1 isa longitudinal sectional View through the device; Fig. 2 is a sectionalong the line 22 of Fi 1 looking in the direction of the arrow; Fig. 3 is a section along the line 33 of Fig. 1 looking in the direction of the arrows; Fig. 4 is a view of the upper end of the device; and, Fig. 5' is a transverse sectional view showing a portion of the heating tube.

In carrymg out my invention I provide suitable bearings 2 and 3, which are carried by the upper and lower stationary plates 4 and 5 respectively. A series of tubes, such as those shown at A, B, C, etc., have their 5, these ends being expanded, as shown in Fig. 1,. so as to secure the tubes firmly in position. Collars 43 and 5 are secured to the shaft in order to prevent longitudinal movement of the shaft with respect to the Specification of Letters Patent.

' plates or heads 4 and 5. The shaft 1, however, has a free rotary movement. with respect to these heads.

Secured to the shaft by means of the set screw 16, or in any other suitable manner, is

; a revoluhle plate 7 having an extension 8 ar- 1 ranged to be connected by means of a union 9 with a tube 10. The union 9 also rmits the tube 10 to swivel or turn wit in the union during the motion of the extension. This tube 10, as will be seen from Fig. f2, extends upwardly and telescopes in another tube 11. The latter is. supported at its top by means (not shown) which will permit it to have a'slight'movement from side to side. At the lower 'end of the shaft is 1 a plate 12 which is similar in construction to the plate 7. It is provided with an outlet tube 13 connected bya union 14 with a dis charge pipe 15. The plates 7 and 12 are so arranged that when the tube section 8-is in registration with any of the "tubes, as for instance tube A, (see Fig. 1) thesection 13 1 will he in registration with tube B. In Fig. 31 have shown the general arrangement of j the tubes which it will be seen are equal distances from the central shaft 1.

Each of the tubes A, Band C, etc., is surrounded by' an outer tube, such as that shown at a, b, 0, etc. The outer tubes are each provided with inlet pipes 16, by means of Which steam may be admitted into the space between the inner and outer tubes. The bottoms of the outer tubes have drain pipes 17,

1 by means of which the water of condensas 'tion may be drawn oif. These drain pipes 17 empty into a, common discharge pipe 18.

The outer tubes are lined preferably with some heat insulating material 19, such as asbestos, as shown in Fi 5'.

The plate 7 is provided with pins 20,

which project through slots 21 in an annular plate 22. The latter is provided on its periphery with a series of ratchet teeth 23 arranged to be engaged by a pawl 24 at the lower end of a piston rod 25. The latter bears a spring 26 which keeps the pawl 24 in engagement with the ratchet teeth. The rod 25 may be reciprocat-ed by any suitable means. The annular plate 22 is provided with a stop member 27, which is arran ed to project into a slot 8 in the tube sectlon 8,

when the plate 22 is moved in the manner hereinafter described. The device is 'supported by means of hangers 28, or it may be supported in any other suitable manner.

The plate 7 bears a spring 29, which engages a pin 30 on the annular plate or ring 22.

From the foregoing description of the various parts of the device theoperation thereof may be readily understood. 7

The cans of fish, vegetables or other material to be cooked are designed to be delivered by means of the pipes 11 and 10 into the tube section 8. Consider now Fig. 1; the tube section 8 registers with the upper pipe A and, therefore, the cans may slide longitudinally into the pipe A until they are stopped by means of the plate 12. The rod 25 is now reciprocated and the pawl will be moved from the full line position shown in Fig. to the dotted line position. This will cause an initial movement of the annular'ring or plate 22 until the ends of the slots 21 engage the pins 20. The effect of this initial movement will be to cause the stop 27 to enter the tube section 8, thereby preventing the movement of any more cans out of the tube 10 until the latter has been shifted to register with the tube B. As stated before, when the tube sect-ion 8 is in registration with the pipe A the discharge tube section 13 is in registration with the pipe B and, therefore, the cans will have passed out of B into thedischarge pipe 15. When now the rod 25 is further drawn upwardly the ends of the slots 21 will engage the pins 20 on the plate 7 and will, therefore, cause the revolution of the plate 7. Since this plate and also the plate 12 are firmly secured to the shaft, the plate 12 will also be rotated to be brought into registration with the next tube 0. Now on the retraction of the rod 25 the annular plate 22 will be rotated in the reverse direction far enough to permit the withdrawal of the-stop member 27, this being occasioned by the action of the spring 29. The friction of the parts will prevent the plate 22 from further backward revolution, while the pawl 24 is moving to the next tooth, or, if desired, a dog may be provided to positively engage the teeth to prevent the backward revolution of the plate 22 when it has reached the end of the slot 21. The cams may now be dehvered to the tube B, while those which were in the tube 0 were of course discharged into the tube 15, when the latter came into registration with the tube 0.

The reciprocation of the rod 25 is of course timed to allow the contents of the cansto be cooked. Obviously some articles requ re a longer and some a less time for cooklng, and the rate of reciprocation of the rod 25 should be gaged accordingly. The amount of steam, the pressure and temperature thereof may also be varied in accordance with the work to be done.

It will be apparent that as the plate 7 revolves to bring the tube section 8 into registration with the various pipes the tube properly gaged the cooking of the contents of the cans is continued automatically and does not need any further attention.
